Experiment 3 Pilot Analysis (round 2)

This document was last updated at 2019-08-09 15:44:33.

This document is dedicated to conducting a descriptive summary of the survey data from the Experiment 3 pilot. Briefly, this pilot was conducted mostly to assess the clarity of instructions. Twenty five subjects were recruited for the pilot. This is the second round of piloting, where the stimuli have been simplified such that we are no longer displaying the absolute effort units. The stimuli now look like the following:

And the instructional video was modified to be the following:

The survey that was given to subjects (which is the same as the last round of piloting) can be seen below:

d <- read.csv('../../data/demo.csv')

d$clarity <- factor(d$clarity, levels = rev(c('very-clear', 'somewhat-clear', 'neutral', 'somewhat-unclear', 'very-unclear')))
d$unitFeel <- factor(d$unitFeel, levels = c('no-relationship', 'weak', 'moderate', 'strong'))
d %>% 
  group_by(clarity) %>% 
  summarize(Count = n()) %>% 
  mutate(Relative.Proportion = Count / sum(Count))

ggplot(d, aes(x = clarity)) +
  geom_histogram(stat = 'count', fill = 'light grey', color = 'black') +
  scale_x_discrete(drop = FALSE, labels = c(`very-clear` = 'Very Clear', `somewhat-clear` = 'Somewhat Clear', `neutral` = 'Neutral', `somewhat-unclear` = 'Somewhat Unclear', `very-unclear` = 'Very Unclear')) +
  labs(
    x = 'Clarity', 
    y = 'Count'
  ) + 
  theme_bw()
